SRS is available for take off phase and for GA phase for vertical plane. Once SRS is engaged in take off it cannot be changed to GA phase unless it is disengaged first (to CLB/OP CLB, V/S0) before it can be engaged again another mode like GA. OEI and engine fire have different implications at. EO ACC ALT is like scratch pad, it is a reminder. It does not enter into the computer. When engine failure below AEO ACC ALT is detected by FADEC the AEO ACC ALT is dashed and SRS remains engaged till pilot changes to any of the modes mentioned above. Engine fire is not detected by FADEC till the engine is shut down and before that if you reach ACC ALT then it will change to CLB or OP CLB for take off and OP CLB for GA(CLB is NA for GA). After change of SRS to any other mode if you select TOGA it will engage GA mode. SRS is a managed speed mode, when in GA mode you go speed select it will disengage to OP CLB mode similarly if you are in approach with select speed on engagement of GA speed will become managed.
